Automatic Assistance Method for Disease Diagnosis Based on a Deep Learning Fusion Model and Chinese Electronic Medical Record

Abstract

Extracting disease characteristics from large-scale Electronic Medical Records and achieving disease-assisted diagnoses have significant research value. Due to the complex multi-feature items and unbalanced data distribution of Electronic Medical Records, feature representation and disease diagnosis are difficult. Our study proposes a deep feature fusion (DFF) model based on the feature partition and deep feature extraction. First, the feature partition is performed, and different feature representation algorithms are adopted for different types of data. The discrete feature items are directly mapped into real-valued vectors, and the continuous feature items are represented by GCNN-based VAE. Then, the two parts are fused. Finally, the assisted diagnosis results are output through a supervised learning classification method based on the XGBoost framework. The dataset of our study is from the 18,590 real and effective clinical Electronic Medical Record of Huangshi Central Hospital. The experimental results show that the method can perform clinical Assisted diagnosis accurately and efficiently, which are superior to some other state-of-the-art approaches, can better meet the needs of practical clinical diagnosis applications.
